A certain group of car dealerships agreed to donate x dollars to a Red Cross Chapter for each car sold during a 30-day period. What was the total amount that was expected to be donated?
I. A total of 500 cars were expected to be sold
II. Sixty more cars were sold than expected so that the total amount actually donated was $28,000
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
EACH statement ALONE is sufficient to answer the question asked.
Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.
Option C is the correct answer.
We need two things:
2. Total number of cars.
Statement I is insufficient: Total of 500 cars sold. Fine! But, we don’t know x, so donation amount cannot be computed. (Not Sufficient)
Statement II is insufficient: Let N be total number of cars: (N + 60)X = 28000
Again we don’t have N and X – Not Sufficient
Combine I and II,
560 * X = 28000
X = 2800 / 56 = 50
Total Contribution = 25000.
